I have the same think, started with frequent urination, and then moved to sharp pain for a few seconds in the groin area. Went to urologist, had blood tests that were fine, urine test found some blood, PSA was fine, ultra sound was fine, pielography was fine, sperm culture showed infection on my prostate. Took antibiotics for 3 weeks and i had a sperm culture again that showed i was fine. The pain still continues, not every day, it comes and goes, sometimes i get this frequent urination, i am terrified, i get nausea, dizziness, I am thinking about it every day, every minute and i get worst. Everybody thinks i am crazy and i make it up. I will visit a psychologist probably will help me to get it out of my head.
